摘要： An apparatus for classifying a true target includes a signal processor configured to perform range processing on an input signal in a fast time direction and Doppler processing on the input signal in a slow time direction to output an output signal in a range-Doppler domain, a detector configured to output a hit by detecting a target signal within an output signal on which the range processing and the Doppler processing have been performed in the signal processor, a total energy calculator configured to calculate a total energy value of the input signal of the signal processor in the slow time direction or a total energy value which is a sum of power spectra of the output signal of the signal processor in the Doppler direction, a Doppler ratio value calculator configured to calculate a Doppler ratio value of the hit detected in the range-Doppler domain using the total energy value, and a false target remover configured to compare the Doppler ratio value with a threshold value and determine a hit having the Doppler ratio value smaller than the threshold value as a false target.
